-serrinrafereoanraa To ahi 'whom it may concern i Ee it known. thatwe, E. R. Henn am. ifi'iiznn H. Tower, oi" Syracuse. in the eonnty of Ilia niega, and State of New York, nave invented a new ainfvalnable Improvement in Striving-Machines; and, rre rio hereby deeiare that the following is a 'nii, einer, and exact desoription of the construction and operation of the naine, reference being had to the annexed drawings, making a partei' this specification, and to the' letters and figures of reference marked thereon.

Figure l of the-drawings is a @entrai vertical longitndinaisection of our invention.

Figure 2 is a top view of the same. A l

Uur invention relates to sznvingnnaehines, and consiste in novel arrangement of devices intended to serve as lan eieient apparatus in the. oe-enpation oi" sawing woori into lengths.

The ietter if the drawings designates'tliefane of the machine, eonsistingnf the nprighiii. A' n', bedpieees B B, ties G C, and girdersl E.

' G designates the saw, fastened between the 'aws` formed in the end-0i' the sliding bar H, whieh siides in a groo ve in the hangingr guide-rame ML Y The other end 0i' the sliding bar Ii is pirated to the pinnen e, which is adjustable, and pivoted in turn to the perpendicular arin o of the iever V.

rihe lever V consists of the horizontai bar or fnlcram q, horizontal arm o', and perpendicular arm o.

The fulerum g is pivoted, at the ends, inthe nprightsa' a'.

The horizontal arm 'v' of the level' is operated through the pitman ryby the mank-shaft` s', on one end of which is keyed the fiy-wheel t, and, on the other end, the spur-wheel u, which gears with the annular wheel K, operated by the pinion l, to which is fastened the handful-ank L.,

The annular Whe-e1 K turns on the round bolt i, which is fastened to the upright- A by the nut n.

Upon the outer end 'of the holt or shaft' secured any arm, p, extending at right angles to the holt t', and inthe direction of the teeth el' the annular wheel K. To the end of A the arm p is pivoted the pinion l, to which is secured, eccentrienlly, the hand-crank L, by

operating which the machine is set in motion.

M designates the descending frame, hy means of' which the Vsar/is guided down through the lng. It eonsisin ofl a horizontal shelf, grooved crosswise, for

vthe passage to. and fro of the sliding ar fhe ends of this shelf are dovetaileii into upright oheehn'k i, grooved perpemlienlarly, on the outside, to fit the gnifieposts a o, on which they eiide.

Lengtl1wise,niong the middle o the apnea snrtee of the ehoif M, is seenred the rib f, iinitened aieo at eeen and hy being iet into the cheeks it il.,

,Ente thin rin, at each end, are fastened the screws or ringhnii'e e e, to which in ettaeheii n hail, nir, iinked above, at its trentini peint, to the emi the ii"'ng f. .mm-amm@ n order to form a feier-um for this lever, a support, Iii, is fastened to the centre of the girder E. S designates a spring-catch, 'fastened to the @entre of the girder E, in sneh a position, that when the end of the. lever F is brought down, thereby raising ythe saw to its highest'elevation, it will eatoh and hold the lever-end, thus holding np the saw until it is brought over the log te be sawn.

The operation of this nlaohine is aeollows: The saw being raised by the lever F, this'rnaeliine is brought alongside the ieg' or tree which is tor'be san'n. in snel: a manner that the saw wili extend over it. ,The spring S is nony drawn back, releasing the lever F, and` allowing the gnideshelf M to descend until the san' rests on. the top of the log. The omni; L is now turned by hand, rotating thepinion i, which in turn causes the annular wheel K to reijolv, by enof the teeth of the wheel 1f., at the same time engagging with the pinion An, causes it to revolve, thereby turning the crank-shaft s', which, through-the rightangled lever V, and pitmen fr and e', gives the saw Glthe necessary motion, the sliding bar-,Hkeeping the saw always horizontal.

`in the nee ofthis machine, there is'no necessity of raising the log on-niriiiis ,it can he sawnit lies on lthe ground, and the saw will pass entirely'tln'ongh the log, square down to theV ground.

The pitni'an s 'is adjustable on the perpendienlar arm of the right-angled lever V,so that this arm may be made longer or shorter, thus regulating the amount of power communicated to the saw, and the length of its stroke.

What we claim as our invention, and desire to secure by Letters Patent, is-

l; In combination with the pendent guide M, slidebar H, and pitnian .3', the adjustable right-angled lever "i", const-minted and arranged te operate as specified.

2. The arrangement, herein` showinoi' thedouhieriingannnlar wheel'K, pinions Z and u, crank-shaft s', and crank L, for operating a cross-ent saw, as specified.

3. The sawing-machine, herein described, having x the pinions l and u gearing with the donhlerim annu` lar wheei K, orank-shai`t s,pit1nanr, right-angled lever V, adjustable pitnian z, sliding har H, and pendent sliding guide M, with liiting-lever F, and spring-mieli S, all consti-noted and arranged 'to operate a emes-oni;

fsaW, as specified.

.In .testimonythat we claim the ahorn, we have hereunto onheeribed oinnamee, in the inneren@ iiiro witnesses.
